Located on Wheatsheaf Lane, Staines, Surrey – just to the west of London – it has been the home of Staines Town since it was purchased in 1951. The ground has a total capacity of 3,000, with 300 seated and 800 in covered terrace.
Prior to the semi-finals, 2011-12 FA Youth Cup home matches were played at Staines, and in 2012 Staines Town partnered with Chelsea Ladies, with Wheatsheaf Park to host all Ladies matches in 2012. 
Wheatsheaf Park is approximately a one mile walk south from Staines railway station, which is served by regular South West Trains services from London Waterloo, and two trains per hour to Windsor & Eton Riverside, Weybridge and Reading respectively.
